When it comes to selecting the right Miniature Circuit Breaker (MCB) for your commercial or industrial needs, understanding the technical specifics is crucial. The S800HV Series MCB offers a robust solution designed to meet demanding requirements.
This single-pole MCB features a rated current of 13 A and operates efficiently within an operational temperature range as low as -25°C, ensuring reliability in various environmental conditions. It supports both 580 VAC and 1000 VAC applications with a rated insulation voltage of up to 1000 V, making it versatile for different electrical setups.
The S800HV boasts a rated impulse withstand voltage of 8 kV, providing protection against transient overvoltages. Its breaking capacity stands at 4 kA at 1000 VAC, while the short circuit capacity is measured at 2.5 kA—key metrics that ensure safety under fault conditions.
With its K-type release curve, this MCB is tailored for applications where high inrush currents are expected without nuisance tripping. This feature makes it particularly suitable for motor-starting circuits and other inductive loads commonly found in industrial settings.
In terms of construction, the device measures a compact width of 27 mm with dimensions including a height of 142 mm and depth of 82.5 mm. It incorporates screw clamp terminals capable of accommodating cable cross sections up to 50 sq-mm on both top and bottom connections, secured with a tightening torque of 3.5 N-m.
The degree of protection offered by this unit is IP20, safeguarding against solid objects larger than 12 mm but not water ingress—a typical specification for indoor installations where moisture exposure isn't prevalent. Additionally, it adheres to standards like AS/NZS 60947-2 and UL1077 ensuring compliance with Australian safety regulations.
Mounting on DIN rails allows easy installation or replacement within standard electrical panels while maintaining system integrity through its RAL7035 grey housing—aesthetic yet functional design choice that blends seamlessly into most control cabinets.
The overvoltage category III rating further signifies that this breaker can handle substantial overvoltage spikes typically seen in fixed installations such as distribution boards or industrial equipment interfaces.
For those seeking an efficient balance between performance specifications and practical application benefits in their electrical systems across commercial or industrial environments—the S800HV Series MCB presents itself as a reliable candidate meeting stringent operational demands effectively within its class parameters.
