Stag Isolator 4 Pole, 32 Amp Enclosed IP65 (IS4P32)

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

1. Ensure the power supply is fully isolated before starting installation.
2. Mount the isolator using the external mounting points on the enclosure.
3. Confirm the rotary handle is in the OFF position (lid interlocks prevent opening while ON).
4. Select appropriate cable entry points and open the required gland knockouts (M20 or M25).
5. Connect incoming supply cables to terminals L1, L2, L3, and N.
6. Connect outgoing load cables to terminals T1, T2, T3, and N.
7. Terminate the earth conductor using the additional earth connection.
8. Tighten terminal screws to the recommended torque of 2 Nm.
9. Close the enclosure lid and secure it with stainless steel screws.
10. 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.
