The S800S series MCB (Miniature Circuit Breaker) is a robust choice for professionals in the commercial and industrial sectors looking for reliable electrical protection. With its rated current of 63 A, this MCB is designed to handle substantial electrical loads while ensuring safety and efficiency.
One of the standout features of this MCB is its impressive breaking capacity of 50 kA at 230 VAC, making it suitable for environments where high fault levels are expected. The device also boasts a rated impulse withstand voltage of 8 kV and a rated insulation voltage up to 690 V, providing strong resilience against electrical surges and maintaining operational integrity under demanding conditions.
This circuit breaker operates efficiently across standard voltages of 230/400 VAC with a frequency range of 50/60 Hz. It offers electrical durability with an endurance rating of up to 6000 cycles, ensuring long-term reliability in various applications. Furthermore, it maintains power loss at just 6.4 W, contributing to energy efficiency within your system.
The S800S series adheres to rigorous standards such as AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077 approvals, confirming its compliance with Australian safety regulations and international quality benchmarks.
For installation flexibility, the MCB features a screw clamp terminal type that accommodates cable cross-sections up to 50 sq-mm on both top and bottom connections. It requires a tightening torque of about 3.5 N-m which ensures secure connections without compromising ease-of-installation.
With dimensions measuring at a width of only 27 mm per pole and overall height and depth being compact at approximately 95 mm by 82.5 mm respectively, this unit fits comfortably into various setups without consuming excessive space on DIN rails.
The housing colour in RAL7035 grey provides a neutral aesthetic that blends well with most equipment panels while offering an IP20 degree of protection for basic ingress safety against solid objects larger than fingers.
Designed specifically for commercial and industrial use cases, it supports environments categorized under pollution degree IP3 indicating suitability even when exposed to certain levels of contaminants typical in industrial settings.
Lastly but importantly from an operational perspective is its C curve type characteristic which allows moderate tripping times ideal for handling inductive loads commonly found in motors or transformers thus preventing nuisance trips whilst safeguarding circuits effectively.
