TEYD2070B - 70Amp Circuit Breaker

TEYD2070B - 70Amp Circuit Breaker

The TEYD2070B is a 2-pole, 70-amp thermal magnetic circuit breaker with a bolt-on mounting design and a non-interchangeable trip unit. Built for 480Y/277V Class systems, it helps protect electrical circuits from overloads and short circuits in commercial and industrial power distribution equipment. With interrupting ratings of 25 kA at 480 VAC and 65 kA at 240 VAC, this breaker is well-suited for applications where higher fault-current protection is required. The bolt-on connection provides a secure installation in compatible panelboards, while the factory-calibrated trip unit delivers consistent performance without field-adjustable settings. Whether you're replacing an existing breaker or servicing electrical equipment, the TEYD2070B is a practical choice for maintaining safe, reliable circuit protection.
