When it comes to selecting a reliable Miniature Circuit Breaker (MCB) for commercial and industrial applications, the S200M series stands as a robust choice. This MCB is engineered to meet stringent standards, providing dependable protection in electrical circuits.
The MCB is rated for a current of 50 A and operates efficiently within a voltage range of 230/400 VAC. It boasts an impressive breaking capacity of 15 kA at 230 VAC, ensuring it can handle high fault levels effectively. Designed with safety in mind, the device features an IP20 degree of protection, safeguarding against solid objects larger than 12 mm.
Constructed to endure tough conditions, this MCB offers electrical durability up to 10,000 cycles. Its rated impulse withstand voltage is set at 4 kV while maintaining a rated insulation voltage of 440 V. The unit complies with AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077 standards, underscoring its adherence to quality benchmarks.
For ease of installation and secure connections, the MCB uses screw clamp terminals capable of accommodating cable cross sections up to 35 sq-mm on both top and bottom ends. With a tightening torque specification of 2.8 N-m, you can be assured that connections remain steadfast under operational stresses.
The compact dimensions—17.5 mm width by 88 mm height by 69 mm depth—make this breaker suitable for space-constrained environments without compromising performance or accessibility. It mounts conveniently onto DIN rails and supports ambient operation temperatures ranging from -25°C to +55°C while being able to withstand storage temperatures between -40°C and +70°C.
Designed with practicality in mind, the S200M series features D curve characteristics suitable for protecting inductive loads such as motors or transformers found commonly in industrial settings. The housing color is RAL 7035 grey which blends seamlessly into most control panels.
Whether you're updating existing systems or designing new ones from scratch, this MCB provides peace of mind with its reliability and compliance with international safety standards. It's not just about meeting technical requirements; it's about exceeding them through thoughtful engineering tailored for demanding environments where downtime isn't an option.
This combination of features positions the S200M series as an ideal solution for those seeking efficiency without compromise in their circuit protection needs within commercial and industrial spaces.
