S203-C Miniature Circuit Breaker C-Char.3P

Motor Branch Circuit Protection

Motor circuit protection describes the short-circuit protection of conductors supplying power to the motor, the motor controller, and motor control circuits/conductors.
430.52 provides the maximum sizes or settings for overcurrent devices protecting the motor branch circuit. A branch circuit is defined in Article 100 as “The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).”

Description

System pro M compact S200 miniature circuit breakers are current limiting. They have two different tripping mechanisms- the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in different characteristics (B-C-D-K-Z)- configurations (1P-1P+N-2P-3P-3P+N-4P)- breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 63A). All MCBs of the product range S200 comply with IEC/EN 60898-1- IEC/EN 60947-2- UL1077 (for this code purchased in South America there is no UL certificate)- allowing the use for residential- commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.
