MidNite Solar MNPV3 PV Combiner Enclosure

Type 3R PV combiner enclosure with a 60 A positive bus and space for three applicable MNEPV breakers or two touch-safe fuse holders; protection devices are sold separately.

Best for: Outdoor PV string combining after selecting exact voltage-rated protection devices, preserving mounting and sealing requirements, and checking conductor and torque instructions.

Manufacturer document conflict

Conflict: the exact MNPV3 page and Rev. J manual describe 300 VDC breaker configurations, while the same current product page lists 150 VDC MNEPV breaker accessories; 600 VDC requires touch-safe fuse holders and correctly rated 10 x 38 mm fuses

Conditions: Selection Gate: verify_exact_breaker_suffix_and_voltage_rating · Publish Numeric Max: No

Do not apply the affected specification until the exact current document or manufacturer guidance resolves the discrepancy.
