Technical data and performance

Parameter	Specification
Rated Voltage (V)	24~1500 DC
Shell Rack Current (A)	100, 160, 250, 400, 500, 600
Number of Poles (P)	1, 2, 3, 4
Breaking Capacity (kA)	20
Standards Compliant	IEC/EN60947-2, GB 14048.2
Derating	When the ambient temperature exceeds 40°C, the overload protection characteristics of the product will change little with temperature, and lr needs to be set to ensure use in a high-temperature environment. When the altitude is above 2000m, it is necessary to consider the change of dielectric strength and the factor of air temperature drop, so derating is also required.
Temperature	-25~+70
Pollution Level	3
Ambient Temperature (°C)	No more than 50%
Altitude (m)	2000
Wiring	Series, Parallel
Product Accessories	Auxiliary contacts (OF, SD, SDE), trip coils (MX, MN), etc.
Installation Method	Fixed, Plug-in, Draw-out
