Siemens AG 3VL2706-1SG36-0AA0-Z Circuit Breaker

Siemens 3VL2706-1SG36-0AA0-Z is a VL160N molded‑case circuit breaker designed for line protection in low‑voltage systems up to 415 V AC. It is a 3‑pole, fixed‑mounted device in the VL160/3VL2 family that uses the ETU22 trip unit with LSIG protection for three‑wire, three‑phase circuits. The unit is rated for a nominal current of 63 A, with an adjustable current setting (IR) from 25 A to 63 A, and a short‑circuit current rating (Icu) up to 40 kA at 415 V. Termination is via screw connections for three wires (S/3WIRES IN=63A). This model is specified without auxiliary or alarm contacts and is commonly used in generator protection and distribution applications where compact, three‑pole protection on the VL160 frame is required.
