Air tight chassis connector, B-type for power-out, flat tab terminals.
Industrial Connectors / PowerCon®
Locking 3 conductor equipment AC connector with contacts for line, neutral and pre-mating ground
contact. Fast and easy locking system. High current capacity (20 A rated). Extremely robust and
reliable. Meets all prevailing safety standards. UL recognized, VDE certified and SEV approved. Very
good cable handling and protection. Note: The PowerCon® is a connector without breaking capacity,
i.e. the PowerCon® should not be connected or disconnected under load or live!

CODING
With the two non-interchangeable types of connectors (A-type, B-type) it is impossible to produce a
short circuit. Mating connectors (combination) are identified by mechanical keyways and by color:
- A-type (POWER-IN)
Cable connector: blue
Chassis connector: blue
- B-type (POWER-OUT)
Cable connector: grey, with blue bushing
Chassis connector: grey
