Stag Isolator 4 Pole, 32 Amp Enclosed IP65 125x100x85mm (IS4P32)
Description
The Stag IS4P32 Enclosed 4 Pole 32 Amp Isolator is a rotary isolator switch designed to safely disconnect AC power from circuits or equipment. It is commonly used in industrial, commercial, and residential electrical systems for safe isolation of low-to-medium current circuits.
The IS4P32 Enclosed Rotary Isolator is a robust 4-pole AC isolator for three-phase and neutral electrical circuits. Rated at 32A and compliant with IEC / EN 60947-3, it is suitable for industrial, commercial, and renewable energy applications. Its durable IP65 polycarbonate enclosure ensures protection against dust and water ingress, making it ideal for indoor and outdoor use.
Installation
- Ensure the power supply is fully isolated before starting installation.
- Mount the isolator using the external mounting points on the enclosure.
- Confirm the rotary handle is in the OFF position (lid interlocks prevent opening while ON).
- Select appropriate cable entry points and open the required gland knockouts (M20 or M25).
- Connect incoming supply cables to terminals L1, L2, L3, and N.
- Connect outgoing load cables to terminals T1, T2, T3, and N.
- Terminate the earth conductor using the additional earth connection.
- Tighten terminal screws to the recommended torque of 2 Nm.
- Close the enclosure lid and secure it with stainless steel screws.
- Rotate the handle to the ON position to energize the circuit.
Operating Features
- 4-Pole Isolation: Disconnects all three phases and neutral simultaneously.
- Lockable Rotary Handle: Can be padlocked in the OFF position for maintenance safety.
- Interlocked Enclosure Lid: Prevents access to live parts when the switch is ON.
- Flame-Retardant Enclosure: Enhances fire safety.
- IP65 Protection: Dust and water jet resistant for indoor/outdoor use.
Notes
- Installation must be done by a qualified electrician according to local regulations.
- Verify correct phase rotation and neutral connection before energizing.
- Intended for isolation purposes, not for frequent load switching.
