The Motor Circuit Breaker 1.1-1.6A is a three-pole motor protective circuit breaker from the 3RV10 range, designed for reliable switching and protection of induction motors and load feeders. This motor protection switch combines short-circuit protection, motor protection, and system protection in a compact form factor, making it suitable for industrial control panels, machinery, and electrical distribution applications where dependable motor safeguarding is essential. Built for long-term stability, the unit is optimized for load feeder applications and supports manual operation with a reset function. It also features a lockable OFF position for added safety during maintenance and servicing. With a rated operational voltage of up to 690V and short-circuit withstand capability up to 50kA at 400V AC, it is engineered for demanding industrial environments. The breaker is suitable for use in applications such as emergency stop switching, transformer protection, and fuse monitoring, in addition to standard motor protection. It offers a maximum switching frequency of 15 operations per hour and a mechanical life of up to 10^5 operations, supporting repeated use in industrial systems. The ambient operating temperature range of -20°C to +60°C further enhances its suitability for varied installation conditions. Please note that this product is in obsolescence mode and is scheduled for discontinuation by the manufacturer. Buyers are advised to review the manufacturer-recommended alternative or refer to the cross-reference list for the appropriate upgrade path. When installing in dusty or damp environments, proper enclosure protection is recommended to ensure reliable performance and protection from environmental factors.
