1 / 7PV Combiner Box
PV Combiner Box 4 PV Array Inputs, 63A DC Breaker, 15A Fuse & 40kA SPD (Steel, with Safety Lock)
The PCB-M4in-04 is a 4-input PV combiner box designed for commercial solar arrays where security and ruggedness are priorities. It integrates a 63A DC circuit breaker for overload and short-circuit protection, 4脳15A PV fuses for independent per-string protection, and a 500V DC surge protection device rated at 40kA max discharge current to defend the system against lightning-induced transients. The robust steel enclosure offers high impact resistance, is rated IP65 against dust and water, and ships with a safety lock and key to prevent unauthorized access. Suitable for outdoor installation on both grid-tied and off-grid PV systems.
