The Megger B10E Power Supply Unit is used to supply voltage to the Circuit Breaker (CB) coils and spring-charging motor during installation and/or field service. Since the high-quality voltage available at the coil outputs is very load-independent, the power supplied resembles what is encountered under normal operating conditions. Circuit breaker functionality thus remains virtually unchanged. B10E enables you to test CB functions easily at the specified voltage levels.

The compact Power Supply Unit Megger B10E provides reliable assistance to those who do maintenance on high-voltage breakers. The control panel's intuitive layout makes it easy to operate, and the built-in thermal cutout and overload protector make it safe to use. The Megger B10E has been developed in collaboration with breaker manufacturers and testing personnel.

Continuously variable 24-250 V AC or DC output.
Separate outputs for close coil, trip coil and spring charging motor voltage.
