Electrical power plug C20 Bachmann 917.173, 250 V, 16 A, thermoplastic, black

Bachmann 917.173 is a C20 electrical power plug designed for alternating current mains up to 250 V and a maximum current of 16 A. The plug features a thermoplastic housing in black and is intended for secure power connections where a C20/C19 mating interface is used. It is suitable for line assembly with cables up to 3G 1.50 mm2 and includes a kink protection nozzle to reduce strain at the cable entry. The design provides an earthing contact compatible with C19 inlets and is made for use in environments such as server racks, professional power distribution units and industrial equipment.

Advantages

The thermoplastic construction offers electrical insulation and resistance to common mechanical stresses while keeping weight low. The plug supports cables up to 3G 1.50 mm2, allowing straightforward connection with standard flexible power cables. Integrated kink protection at the cable entry reduces the risk of conductor damage and extends cable life. The earthing contact conforms to the C20/C19 mating system to ensure reliable protective earth continuity during use.

Suitable for

• Server racks and data centre power distribution
• Professional power distribution units (PDUs)
• Industrial control cabinets and equipment
• Audio–visual and broadcast installations requiring C20 connections
• Appliances and devices specified for 250 V, 16 A C20 inlets

Key specifications

• Rated voltage: 250 V AC
• Rated current: 16 A
• Connector type: C20 (mating with C19 inlet)
• Housing material: thermoplastic (black)
• Cable capacity: up to 3G 1.50 mm²
• Strain relief: kink protection nozzle for line assembly

How to use

Prepare the cable by stripping the outer sheath and individual conductors to the lengths recommended by the manufacturer. Insert conductors into the corresponding terminals and secure them following the torque and fastening instructions provided with the plug. Ensure the kink protection nozzle is positioned over the cable and tightened to provide strain relief. After assembly, verify continuity and correct earthing before connecting the plug to a live C19 inlet. Do not use the plug with damaged conductors or housings.

Recommendations

For safe, long-term operation, use flexible cables that match the specified 3G 1.50 mm² capacity and perform periodic inspections of the housing, contacts and strain relief. Install and service this electrical connector only by qualified personnel and comply with local electrical codes and standards.
