Why Choose the ABB OTP63B4P 63A 4-Pole Plastic Enclosed Switch-Disconnector?
The ABB OTP63B4P (1SCA022401R4830) is a robust 63 A four-pole plastic enclosed switch-disconnector designed for dependable manual switching and local electrical isolation in industrial, commercial and building services installations. Part of the ABB OTP enclosed switch range, it provides a convenient means of disconnecting electrical equipment from its power supply during planned maintenance, inspection and servicing.
Featuring a four-pole switching mechanism, a black selector-type operating handle and an IP65-rated plastic enclosure, the OTP63B4P is suitable for three-phase installations requiring simultaneous switching of four conductors. Its manual I-O operating mechanism provides clear ON/OFF selection, while the enclosed construction helps protect the switching assembly from dust and water jets when correctly installed.
A distinguishing feature of the OTP63B4P is its PG-threaded cable entry arrangement, with provisions for two PG29 entries and one PG11 entry at both the top and bottom of the enclosure. The unit is supplied with neutral and protective earth terminal facilities and measures 200 × 145 × 90 mm. ABB's enclosed switch catalogue lists operational ratings of 80 A AC-22A at up to 690 V AC and 75 A AC-23A at up to 415 V AC, making correct selection according to load characteristics essential.

Reliable Four-Pole Electrical Isolation with PG-Threaded Cable Entries
The ABB OTP63B4P provides a clearly identifiable local isolation point for industrial electrical equipment. Its four-pole mechanism allows four conductors to be switched together, making it suitable for three-phase installations where a switched neutral is required by the electrical system design. The switch should be selected and connected in accordance with the installation's earthing arrangement and applicable electrical standards.
The black selector-type handle provides direct manual switching between the ON and OFF positions. Its OFF-position padlocking facility helps prevent unintended re-energisation while maintenance work is being carried out. Electrical isolation procedures must still include appropriate verification of the de-energised state and compliance with site lockout requirements.
The IP65 plastic enclosure provides environmental protection for the internal switch-disconnector when installed correctly. It is suitable for locations where equipment may be exposed to dust or water jets, subject to the enclosure's installation conditions and the suitability of the selected cable entry fittings.
Unlike the OTP63B4M, which uses metric cable entry knockouts, the OTP63B4P is equipped with PG-threaded entry provisions. The arrangement of two PG29 and one PG11 entries at the top and bottom allows the installer to select suitable cable routes and glands. Compatible compression glands must be ordered separately, and unused openings must remain properly sealed to maintain the required IP rating.
The OTP63B4P is a switch-disconnector, not an automatic protective device. It does not independently provide overload protection, earth leakage protection or automatic short-circuit interruption. Suitable upstream protective devices must therefore be incorporated into the electrical installation, with the switch selected according to its applicable utilisation-category ratings.
