Limited Time ABB / Trumbull ATT337150 – 150A 2 Pole Molded Case Circuit Breaker

A drop-in replacement for older Trumbull switchboards and GE panelboards, the ABB ATT337150 restores power to aging systems. This 2-pole, 150A molded case circuit breaker is engineered for commercial environments requiring heavy-duty performance. It installs into existing bolt-on enclosures without custom adapters. Officially replaced by the TED124150 for newer setups, this legacy unit is rated 30 kAIC at 480VAC and utilizes fixed thermal-magnetic trip units for consistent LI protection.
