Siemens HEM3M070LU Molded Case Circuit Breaker

Siemens HEM3M070LU is a 3‑pole molded‑case circuit breaker (MCCB) rated for 70 A at 480 V AC, designed for three‑phase distribution in commercial and industrial electrical systems. The unit belongs to Siemens’ HEM3M family in the VL‑Series and is configured with lug terminals for straightforward line connections, conforming to standard 3P, 480 V operation. It delivers thermal‑magnetic protection with a typical short‑circuit interruption rating up to 65 kA at 480 V, making it suitable for protection of feeders and motors in a protected power distribution network. The HEM3M070LU supports optional Motor Circuit Protector (MCP) configurations, including mid‑magnetic trip variants, for motor protection and selective coordination in equipment and control panels. This model is documented alongside other HEM3M070L family catalog numbers in Siemens’ molded‑case breaker literature, confirming it as the 70 A, 3‑pole, 480 V version of the HEM3M070 family with lug connections.
