Three Pole 63Amp Isolating Switch | Kripal UKF3-63

Three Pole 63Amp Isolating Switch | Kripal UKF3-63

The Kripal UKF3-63 is a 415V three-pole 63-amp isolating switch for air conditioners and industrial isolation. The Isolating Switch has an IP56 waterproof polycarbonate housing and meets IEC/EN60947-3 and AS/NZS60947-3 requirements.

Electrical and air conditioning installers working on high-amperage machines typically struggle with safe isolation. Electrical work standards demand padlocked isolators for maintenance or emergency shutdown. Padlock-capable on and off positions and big terminals rated 6–8mm cable make the Kripal UKF3-63 suited for heavy-duty applications on three-phase 415V circuits. The lid-base silica gel seal keeps moisture and dust out in outdoor settings.

Licensed electricians and HVAC contractors like the Kripal UKF3-63 simple sizing: twin 25mm bolted entry on top and bottom mounting blocks allow easy installation on existing conduit runs, with 25–20mm reducers for smaller 20mm conduit. Internal neutral and earth links save termination hardware and ease fault-finding. Kripal UKF3-63 isolates AC compressors, heat pump switchgear, and heavy machinery without voltage loss or performance lag without creative wiring.

Features

Three-pole 63A 415V three-phase isolating switch for air conditioning compressors and industrial gear.

IP66 weatherproofing protects contacts and internal components from water and dust in outdoor and exposed applications.

Polycarbonate enclosure—high-impact polycarbonate body provides insulation, strength, durability, and lightweight handling.

In humid or salty environments, silica gel basket seal between lid and base protects.
Padlockable on and off—padlocking in both positions meets electrical work safety and machinery isolation lockout requirements.

Large termination blocks for 6–8mm cable allow thick cable lengths without crushing or voltage drop in high-amperage applications.

Twin 25mm screwed entries, top and bottom—two mounting block entry points accept 25mm conduit, with reducers for smaller conduit.

If the installation requires smaller conduit, two adapter rings are included to scale down conduit entry from 25mm to 20mm.

Fixed neutral and earth cables inside the enclosure ease three-phase installation and fault detection.

Certified to international and AS/NZS standards for industrial general-purpose isolating switches.

The 84 × 84 × 174mm body is compact and fits in confined areas without the need for big mounting blocks or conduit lines.

Not rated for load breaking, the Kripal UKF3-63 isolator should never switch live machines. Turn off the MCB or circuit breaker before using the isolator.

Where to use

The 63Amp Isolating Switch provides secure three-phase switchable isolation for split system and rooftop AC units, fulfilling installation and maintenance lockout requirements.
Switchgear for heat pumps and heating systems isolates high-amperage heating and heat recovery devices on three-phase power.
The 63Amp Isolating Switch isolates industrial motor loads, pumps, fans, and spinning equipment for safe repair and maintenance.
Outdoor electrical installations—IP66 protection makes the switch suitable for weatherproof cabinets, pole-mounted enclosures, and exposed outdoor switchboards.
Three-phase inverter and battery isolation for medium-voltage DC or AC systems in remote or corrosive areas for renewable energy and solar installations.
Main switch duties on temporary power distribution and standby generator cabinets are handled by the 63Amp Isolating Switch.

The 63Amp Isolating Switch should not be used to switch loads frequently or make or break electrical current under normal load. Only as an isolating switch downstream of a main breaker or motor starter. Never use the Kripal UKF3-63 to switch off equipment under load—the contacts may arc and deteriorate. Use 63A only on three-phase 415V, not single-phase or 240V.
