characteristic

As the main switch of the mechanical equipment
Rated current: full range 15~630A
Voltage level: 550V (15~250A), 440V (250A~630A)
Breaking capacity: E7.5KA, B10KA, S18KA, K35KA
Trip unit: thermomagnetic (distribution protection), single magnetic (motor protection)
Number of poles: 3P/4P
Installation method: Fixed installation, horizontal, vertical and flat installation, does not affect electrical performance. Ambient temperature: -25°C~+70°C, derating should be considered when higher than 50°C (40°C should be considered for derating at 630A)

Advantage

60/100 small frame products for small current and small size applications for OEM customers
160/250A products share a size, easy to upgrade and interchange 400/630A high current products with dual rotary contact design, superior current limiting capability greatly reduces the short circuit current damage to the equipment
The circuit breaker isolation position has a mechanical indication and a reliable indication status
The accessories are modular and can be freely replaced
Complete certification, green: CCC, CE, CCS (100A), RoHS (250A)

application

All OEM industries:
Rubber and plastic machinery, textile machinery, air conditioning, HVAC, machine tools, communication power, printing and packaging, construction machinery, lifting machinery, elevator industry, etc.
