TEYL1070B - 70Amp Circuit Breaker

TEYL1070B - 70Amp Circuit Breaker

The TEYL1070B is a 70-amp, single-pole thermal magnetic circuit breaker with a bolt-on mounting design for your compatible Type TEYL panelboards. It is built for 480Y/277V class electrical systems and helps you protect branch circuits by tripping during overloads or short circuits. The breaker features a non-interchangeable trip, so the factory trip characteristics remain unchanged throughout its service life. With interrupting ratings of 65 kA at 277 VAC and 100 kA at 170 VAC, the TEYL1070B is suitable for applications where higher available fault current is present.
