Product Overview

 

The Allen-Bradley 150-TC1 is an IEC terminal cover designed for Bulletin 150 SMC-50 Smart Motor Controllers. It provides dead-front protection for exposed line-side or load-side power terminals on controllers in the 108–135 A range.

 

In motor control assemblies, power terminals and cable connections can remain exposed during installation or maintenance if suitable protective covers are not fitted. The 150-TC1 provides a physical barrier over the relevant terminal area, helping reduce the risk of accidental contact with energized conductive parts.

 

This accessory is intended for use with compatible SMC-50 controller configurations, including the 150-S108 and 150-S135 device ranges. It is not a circuit breaker, overload relay or motor controller. Its function is specifically related to terminal protection within the motor control assembly.

 

Rockwell Automation identifies the 150-TC1 as an IEC line-or-load terminal cover for 108–135 A devices.

The 150-TC1 can be installed at either the line-side or load-side terminal area of a compatible controller.

Line-side protection

The line side is where the incoming power supply connects to the motor controller. The terminal cover provides a protective barrier over the applicable connection area.

Load-side protection

The load side connects the controller to the motor circuit. The cover helps protect the corresponding power terminal area from accidental contact.

Dead-front design

The cover creates a physical barrier around exposed electrical connection points. Rockwell's product documentation specifies IP2X finger-safe protection when the cover is used with 250 MCM cable. This protection description is conditional on the specified cable arrangement and should not be interpreted as an unconditional enclosure IP rating for the complete controller assembly.

The 150-TC1 is intended for the 108–135 A controller range. It should not be treated as a universal terminal cover for all Bulletin 150 devices.

For the 150-TC1, the documented controller references include:

• 150-S108...
• 150-S135...

The 150-TC2 and 150-TC3 serve larger controller ranges and should not be substituted solely because they belong to the same accessory family.

The 150-TC1 is an accessory rather than an operating component of the motor control circuit. It does not perform switching, motor starting, current regulation or overload protection.

Its role is to complement the SMC-50 controller installation by covering the relevant power terminals.

Typical use cases include:

• SMC-50 controller line-side terminal protection
• SMC-50 controller load-side terminal protection
• Industrial motor control panels
• Solid-state motor starter assemblies
• Replacement of damaged or missing terminal covers
• Maintenance of existing Bulletin 150 installations

 

 

150-TC1 Compared with Other Bulletin 150 Terminal Covers

The Bulletin 150 terminal cover family includes three sizes. The selection depends primarily on the controller's current range.

 

Model	Compatible Device Range	Main Purpose
150-TC1	108–135 A	Terminal protection
150-TC2	201–251 A	Terminal protection
150-TC3	317–480 A	Terminal protection

 

The three accessories share the same general purpose but are designed for different controller sizes. Selecting the correct catalog number is therefore important when replacing a missing cover or completing a motor control assembly.

 

An additional distinction applies to smaller SMC-50 units: Rockwell documentation states that 5–85 A devices have terminal guards supplied as standard, so additional terminal guards are not required for those units.

1. What is the Allen-Bradley 150-TC1 used for?

The 150-TC1 is an IEC terminal cover for SMC-50 Smart Motor Controllers. It provides dead-front protection for the controller's line-side or load-side power terminals.

2. Which SMC-50 controllers are compatible with the 150-TC1?

It is designed for 108–135 A devices, including the 150-S108 and 150-S135 controller ranges. The specific controller configuration should be checked before ordering.

3. Can the 150-TC1 be installed on either the line side or load side?

Yes. Rockwell identifies it as a line-or-load terminal cover, meaning it is intended for the applicable power terminal area on either side of the controller.

4. Does the 150-TC1 provide IP2X protection?

Rockwell documentation specifies IP2X finger-safe protection when the cover is used with 250 MCM cable. This condition should be considered when evaluating the protection level of the installed assembly.

5. Is the 150-TC1 a motor protection device?

No. It is a mechanical terminal protection accessory. It does not provide short-circuit protection, overload protection or motor control functions.

6. What is the difference between 150-TC1 and 150-TC2?

The main difference is the compatible controller current range. The 150-TC1 is for 108–135 A devices, while the 150-TC2 is for 201–251 A devices.

7. How many terminal covers are included in one package?

Rockwell's accessory documentation specifies a package quantity of one for the 150-TC1.

8. Is the Allen-Bradley 150-TC1 discontinued?

No. Rockwell Automation currently lists the 150-TC1 with an Active lifecycle status.

The catalog number 150-TC1 identifies the IEC line-or-load terminal cover for 108–135 A Bulletin 150 devices. Its UPC is 662074052332.

When identifying this accessory for replacement, check both the complete catalog number and the controller's current range. The 150-TC1, 150-TC2 and 150-TC3 belong to the same terminal cover family, but their intended device sizes differ.
