Product FAQs

6 answers
What panelboards accept the ATB36015 circuit breaker?

This legacy E-Frame breaker is engineered to bolt directly into older Trumbull panelboards as well as GE A-Series panelboards, making it ideal for maintaining existing infrastructure without a full panel upgrade.

What is the modern replacement for the legacy Trumbull ATB36015?

The GE TED136015 is the direct cross-reference and modern replacement for this breaker. It shares the same E-Frame footprint, bolt-on mounting, and 15A, 3-pole configuration.

Does the ATB36015 come with terminal lugs?

Yes, this breaker includes factory-installed line and load lugs that accommodate wiring from 14 AWG to 8 AWG, allowing for straightforward termination during installation.

Is the ATB36015 suitable for HVAC equipment?

Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires specialized overload protection.

Can the thermal or magnetic trip settings on the ATB36015 be adjusted in the field?

No, this breaker features fixed thermal and fixed magnetic trip settings. The Long-Time and Instantaneous (LI) protection parameters are factory-calibrated and cannot be modified by the installer.

What type of overcurrent protection does the ATB36015 provide?

It utilizes a thermal-magnetic trip unit with common trip functionality. This ensures that an overload or short circuit on any single phase will simultaneously open all three poles, preventing single-phasing of connected three-phase motors.
