Why Choose the ABB OTP63B3P 63 A 3-Pole Plastic Enclosed Switch Disconnector?
The ABB OTP63B3P is a heavy-duty 3-pole plastic enclosed switch disconnector designed for local electrical isolation and load switching in industrial machinery, motor control systems and low-voltage electrical installations. Part of the ABB OTP enclosed switch range, it combines a robust manual switching mechanism with a protective enclosure and a clearly identifiable black rotary operating handle.
Featuring an IP65-rated plastic enclosure and PG threaded knock-out cable entries, the OTP63B3P provides a practical solution for electrical installations requiring environmental protection and convenient cable routing. Its black selector-type operating handle features ON/OFF indication, allowing operators to identify the switch position quickly during normal operation and maintenance.
Identified by ABB order code OTP63B3P and manufacturer product ID 1SCA022383R3370, this switch is specified in the supplied product description as a 63 A, 3-pole enclosed switch. ABB's catalogue also identifies 80 A AC-21, 75 A AC-22 and 58 A AC-23 switching ratings for the OTP63B3P range, demonstrating its suitability for appropriately selected industrial electrical loads.

Reliable Local Isolation for Industrial Machinery and Motor Control
Enclosed switch disconnectors such as the ABB OTP63B3P provide a manually operated means of disconnecting electrical equipment from its power supply. The switch uses a mechanical switching mechanism to open or close the main contacts, enabling operators and maintenance personnel to isolate connected machinery before inspection, servicing or repair.
The three-pole configuration enables simultaneous switching of three phase conductors, making the OTP63B3P suitable for compatible three-phase electrical installations. Its black rotary selector handle provides clear ON/OFF indication, while the enclosed construction helps protect internal switching components from environmental exposure.
The PG threaded knock-out cable entries allow power and auxiliary wiring to be routed through suitable cable glands. The enclosure provides space for the specified cable entry arrangement, while the included neutral and protective earth terminals support connection of associated conductors. Correct cable gland selection and installation are important for maintaining the enclosure's IP65 protection rating.
For motor and machinery isolation applications, the switch should be selected according to the connected equipment's operating current, voltage, starting characteristics and applicable utilisation category. Suitable upstream overcurrent and short-circuit protection must also be provided as part of the complete electrical installation.
