TEYF2070B - 70Amp Circuit Breaker

TEYF2070B - 70 Amp Circuit Breaker

The TEYF2070B is a 70 Amp, 2-pole bolt-on thermal magnetic circuit breaker for your compatible 480Y/277V Class panelboards. It uses a fixed, non-interchangeable trip unit and is intended to protect electrical circuits from overloads and short circuits. The breaker has an interrupting rating of 18kA at 480VAC and 65kA at 240VAC. A bolt-on mounting design keeps the breaker securely attached to the panelboard, making it a common choice for commercial and industrial electrical systems. The thermal magnetic trip responds to sustained overload conditions as well as higher fault currents, helping you protect connected equipment when abnormal electrical conditions occur. Before replacing an existing breaker, confirm that the part number, type, electrical ratings, and panelboard compatibility match the original installation.
