📊 Product Specification — HAGER 4-Pole Isolator Switch

Typical Models

• Hager SBN463 4P Isolator – 4-Pole modular isolator, ~63 A rating.

• Hager 63A 4P Weatherproof Isolator JG463IN – Weatherproof 40 A 4P isolator (outdoor).

• Hager SBN490 4P Switch Disconnector – 4-Pole 100 A isolator switch.

• Hager HIM404 4P On‑load Switch – Heavy 4P DIN-rail rated device (40 A, IP20).

🔎 What It Does

A 4-Pole isolator switch provides a reliable means to disconnect all 3 phase conductors plus neutral manually, creating a visible and positive break in the circuit. This allows safe maintenance, servicing, or emergency shutdown of three-phase electrical systems. 

⚙️ Typical Ratings & Use Cases

• 40 A – 63 A units: Common for small to medium three-phase loads and distribution boards.

• 80 A – 100 A units: Suitable for larger machines, heavier loads, or larger panel main switches. 

• Weatherproof isolators (IP66): Useful for outdoor installations or harsh environments like industrial yards and exterior equipment rooms. 

📌 Notes / Safety

• An isolator does not provide overload or short-circuit protection — it’s for manual disconnection only. You should use it together with protective devices like MCBs, MCCBs, RCCBs, or RCBOs upstream.

• Ratings should be chosen based on the maximum current and voltage of the circuit being isolated.
