People Electric · Explosion-Proof Motor Starter Distribution Box
Product overview
People Electric BXQ51 is a configurable multi-circuit power and electromagnetic-starter box for AC 380V systems. Each circuit is engineered with the required breaker, contactor, thermal relay and controls; the manufacturer lists five circuit-count choices.
Technical selection summary
| Manufacturer / family | Original People Electric BXQ51 |
|---|---|
| Rated supply | AC 380V; three-phase wiring shown in the reference schematic; confirm frequency/control supplies |
| Documented circuit counts | 2, 3, 4, 6 or 8 |
| Current limits | Main circuit ≤400A; each branch ≤160A. Confirm actual branch ratings, simultaneous loading and main-circuit design. |
| Branch construction | At ≤63A: modular construction with MCB, AC contactor, selector and thermal relay; ammeter/CT optional. Above63A: combined larger enclosure with MCCB, AC contactor and thermal relay, as source. |
| Manufacturer Ex markings | Exde IIB T6; special IIC T6 version as marked with an asterisk. Specify IIC explicitly and verify the supplied assembly. |
| Ingress / corrosion protection | IP54; IP65 special version as source asterisk; WF1 |
| Control options | Local, remote or two-location control as an engineered circuit; actual coil, buttons, indicators and interlocks require confirmation |
| Cable entries | G1 1/2 to G3 source entry range; count, direction and exact size by approved drawing |
| Standards referenced | GB 3836.1, GB 3836.2, GB 3836.3 and IEC 60079 as catalogue; no unobserved certificate is asserted |
This assembly is specified by an approved circuit drawing and component schedule. Catalogue current limits are upper boundaries, not the rating of every possible configuration. Confirm each circuit current/poles, devices, protection coordination, cable entries, actual Ex marking and conformity documentation before ordering. Reference outlines are not a universal final enclosure size.
Typical applications
- Project multi-motor starting and power distribution.
- Local/remote industrial control using a matched branch protection and starter design.
