⚡ At a Glance
- • Connection Reliability: Interlocked 5-pin 3P+N+E layout for secure three-phase connections
- • Best for: Tradespeople, workshops and small factories running 3-phase machinery
- • Not ideal for: Single-phase domestic circuits and appliances using standard plugs
32 amp interlock switched socket for 380-415V three-phase systems. IP44 splashproof rating with the earth at the 6 o'clock position for standardised connections.
Safer plug handling - thanks to interlock switch
An interlock switch is integrated with the socket's switching assembly to control when the 32 amp supply is live. The switch works in tandem with the socket to ensure correct engagement before the circuit is completed.
Reduced chance of improper live connections during routine use, giving greater confidence on site and during maintenance.
Clear phase matching - with 5-pin 3P+N+E configuration
Five-pin layout supplies three phase conductors plus neutral and earth, with the earth positioned at 6 o'clock as specified. The socket accepts only matching 32 amp red 5-pin plugs to maintain correct pairings.
Simplifies wiring and prevents mismatched connections when pairing plugs and sockets in three-phase installations.
Workshop-ready durability - thanks to IP44 splashproof construction
IP44 rating offers protection against splashes and ingress from solid objects larger than 1mm, suitable for typical workshop and site conditions. The socket is specified for 380-415 Volt three-phase applications.
Stands up to everyday trade use, and user feedback highlights a solid build and reliable long-term performance for industrial environments.
