📌 Common HAGER 3-Pole Isolators

• Hager SBN363 3P 63A Isolator Switch – Popular formal isolator rated 63 A for three-phase lines (solid construction). Typically used on distribution boards or control panels. 

• Hager 40A/63A/100A 3P Isolator Switch Disconnector – Set of options (40 A, 63 A, 100 A) for isolating three-phase circuits; great choice for varied loads. 

• Hager Enclosed Weatherproof 3P Isolator IP66 – IP66 outdoor-rated isolator (e.g., 20 A) with housing, perfect for external installations like outdoor machinery or pool equipment. 

• Hager 3P Isolator / Switch Disconnector – General 3-Pole isolator/switch disconnector for use in industrial or commercial electrical panels. 

• Hager 63A/100A 3P Isolator Switch Disconnector – Another variant of the 63 A/100 A isolator line; good for medium to larger three-phase loads. 

• HAGER SBN363 3P 63A Isolator Switch (Alt) – Another listing for the same 3-pole 63 A isolator; good sign of popularity and availability. 

• Hager 3P Isolator 32/40/63/100A – Pack of Hager isolators with multiple current ratings (wide choice). 

• HAGER SBN340 3P 40A Isolator Switch – A 40 A 3-Pole isolator, suitable for smaller three-phase circuits. 

📄 Typical Product Specification – HAGER 3P Isolator Switch

Type: 3-Pole Isolator / Switch Disconnector – manual disconnect device for three-phase circuits. 
Poles: 3P (three conductors, usually 3 phases). 
Rated Operating Voltage: Typically 380 V – 415 V AC (three-phase systems).
Rated Current (Iu): Common options like 32 A, 40 A, 63 A, 100 A (model dependent). 
Rated Short-Circuit Withstand / Breaking Capacity: Varies by model (e.g., 0.384 kA for weatherproof units).
Type of Connection: Screw terminals or bolt connections on larger units. 
Mounting: Surface or panel mounting; some modules suitable for distribution boards. 
Duty: Manual isolating switch – maintains a clear physical open circuit.
Safety Feature: Often interlockable, can be used as a main switch / safety switch. 
Ingress Protection (for weatherproof types): IP66 for outdoor models (dust-tight & powerful water jets).

📌 What a 3-Pole Isolator Does

A 3-Pole Isolator Switch is a manual disconnect device used to safely isolate a three-phase electrical circuit (all three live conductors) from supply power for maintenance or emergency shutdown — it does not provide overload/short-circuit protection but gives a visible mechanical break in the circuit.

Example uses:
✔ Maintenance safety in industrial panels
✔ Isolating three-phase motors and HVAC equipment
✔ Disconnect before working on three-phase machinery
