Lovato SM Motor Protection Circuit Breakers | Adjustable MPCB 0.63-100A

Lovato SM manual motor protection circuit breakers combine adjustable thermal motor protection with magnetic short-circuit tripping. SM1P push-button models and SM1R, SM2R and SM3R rotary-handle models cover different motor currents and panel requirements. Breaking capacity is specific to the selected model and supply voltage, rather than a single rating for the whole range.

Features and applications

• Adjustable current range shown for each order code
• Push-button or rotary operation according to family
• Model-specific short-circuit breaking capacity at 400V
• Optional auxiliary contacts must match the SM frame
