SU200M Circuit Breaker Type K, 1 Pole 4A System Pro M Compact DIN Rail Mount Provides reliable overcurrent protection for singlecircuit lines in control panels and enclosures. Type K protection offers predictable trip behavior for overload conditions on lowcurrent circuits. 1pole design suitable for protecting a single circuit with a 4 A rating. Compact System Pro M Compact form enables efficient integration in modular panel designs. DIN rail mounting allows quick, tool installation and easy replacement in standard electrical cabinets. Spacesaving and compact footprint, ideal for limitedpanel applications. Compatibility and mounting Compatible with System Pro M Compact components for cohesive panel layouts. Designed for standard DIN rails used in control panels and distribution boards. Suitable for installations that require modular, scalable protection in compact enclosures. Performance and durability Delivers consistent overcurrent protection within its 4 A rating. Built for repeated switching in standard electrical cabinet environments (without requiring additional bespoke mounting). Use scenarios Scenario 1: Protect a single lowcurrent automation circuit in a compact control panel for a small conveyor or actuator. Scenario 2: Integrate into a building automation or lighting control enclosure where space is at a and modular protection is needed. Scenario 3: or upgrade a legacy breaker in a System Pro M Compact distribution board to segment a circuit and improve reliability.
