Core Characteristics of Explosion-Proof Distribution Panels:
The defining feature of explosion-proof distribution panels is high customization. Model specifications vary according to specific customer requirements, primarily determined by the following key configurations:
Main Circuit Incoming Current Rating: e.g., 100A, 200A, 250A, 400A, 630A, etc.
Number of Outgoing Circuits: e.g., 4 circuits, 6 circuits, 8 circuits, 12 circuits, 16 circuits, 24 circuits, etc.
Outgoing Circuit Current Ratings: Each outgoing circuit can have different current ratings (e.g., 16A, 20A, 32A, 63A, etc.), utilizing either Miniature Circuit Breakers (MCBs) or Molded Case Circuit Breakers (MCCBs).
Explosion-Proof Marking and Protection Level: e.g., Ex d e IIC T6 Gb / Ex tD A21 IP66 T80°C. Variations in gas group, temperature class, and dust explosion-proof requirements impact model details.
Material: Typically cast aluminum alloy or stainless steel.
Special Functional Requirements: Inclusion of components such as main switch, voltmeter, ammeter, indicator lights, current transformers, surge protectors, dual power transfer switches, remote control interfaces, etc.
Cable Entry Method: Bottom entry, top entry, side entry.
Installation Method: Wall-mounted, free-standing.
Certification Requirements: Compliance with national standards or certifications (e.g., CNEx, NEPSI, ATEX, IECEx).
Model Examples (Illustrative based on common naming logic):
HRMD91-100A-4L: Likely indicates main incoming current 100A with 4 outgoing circuits (default low current rating).
HRMD91-250A-8L(63A*4+32A*4): Likely indicates main incoming current 250A with 8 outgoing circuits (comprising 4 circuits at 63A and 4 circuits at 32A).
HRMD91-400A-12L-MCB: Likely indicates main incoming current 400A with 12 outgoing circuits using Miniature Circuit Breakers (MCBs).
HRMD91-630A-16L(100A MCCB): Likely indicates main incoming current 630A with 16 outgoing circuits (where the main outgoing or specific circuits use a 100A Molded Case Circuit Breaker - MCCB).
HRMD91-200A-6L-ExdIICT6: Explicitly denotes the explosion-proof protection level as Ex d IIC T6.
HRMD91-400A-8L-SS: SS likely denotes Stainless Steel material.
HRMD91-250A-6L-VI: VI likely denotes inclusion of a Voltmeter (V) and Ammeter (I).
