Electrical installation kit with O-I rotary switch 1x16A 4P 400V, 1x16A 250V IP54 — Elektromet 971615

Elektromet 971615 electrical installation kit features an O-I rotary disconnector providing a 4-pole 1x16A switching path at 400 V together with an independent 1x16A circuit at 250 V. The assembly is housed and rated to IP54, offering protection against limited dust ingress and water splashes, making it suitable for indoor and semi-exposed installations. The kit is intended for compact distribution and manual isolation in small industrial, commercial or residential electrical installations where a robust, space-saving disconnection device is required.

Advantages

The kit combines a 4-pole 16 A, 400 V O–I rotary disconnector with a separate 16 A, 250 V circuit in a single IP54-rated enclosure, reducing the need for multiple components. The IP54 protection level allows installation in environments with moderate dust and occasional splashing water without additional protective housing. The rotary disconnector design provides clear visible positions for on/off isolation and straightforward manual operation. Compact dimensions and standardized terminal arrangements simplify installation and wiring in distribution panels or small switchboards.

Suitable for

• Manual isolation of small three-phase motors and circuits in workshops and light industry
• Compact distribution and switching in residential and commercial service panels
• Outdoor or semi-exposed locations where IP54 protection is required
• Temporary or permanent installations requiring a combined multi-pole disconnector and auxiliary circuit

Key specifications

• Switching configuration: 4-pole rotary disconnector (O–I) for the main circuit
• Main circuit rating: 1 × 16 A at 400 V (three-phase switching path)
• Auxiliary circuit rating: 1 × 16 A at 250 V
• Enclosure protection: IP54 (protection against limited dust ingress and water splashes)
• Manual actuation: rotary ON/OFF positions with visible indication
• Mounting: panel or surface mountable enclosure suitable for distribution boards

How to use

Mount the kit in a suitable location within a distribution panel or on a surface that meets IP54 exposure requirements and provides safe access for operation. Make all connections with power disconnected and follow local wiring regulations: connect the incoming and outgoing conductors to the designated terminals for the 4-pole main circuit and to the separate terminals for the 250 V auxiliary circuit. Verify secure tightening of terminals and correct phase orientation before energizing. Use the rotary control to switch the main circuit to the OFF position for safe isolation during maintenance and to ON for normal operation.

Usage recommendations

Perform periodic visual inspections for dust accumulation, moisture ingress and tightness of terminal connections. Ensure the kit is installed where the IP54 rating is sufficient — avoid continuous exposure to heavy rain or jetting water. Follow relevant electrical safety standards and de-energize circuits before performing maintenance.
