Product Technical Specifications

FAQ

Q1: Can the rated current and voltage of the GreenWatt DC1000V 63A molded case circuit breaker be adjusted?

A1: The rated current (63A) and rated voltage (DC1000V) of this product are standard parameters and cannot be adjusted. If customers require different rated parameters, we can customize and produce corresponding DC molded case circuit breakers according to their needs.

Q2: Is this product suitable for outdoor use?

A2: The GreenWatt DC1000V 63A molded case circuit breaker has a protection rating of IP40 (side) and IP20 (terminal). It does not have waterproof or dustproof outdoor protection capabilities and is only suitable for indoor dry environments free of dust and corrosive gases. For outdoor use, a dedicated outdoor protective housing is required.

Q3: What is the product warranty period?

A3: The GreenWatt DC1000V 63A molded case circuit breaker has a one-year warranty. During the warranty period, if the product experiences quality issues not caused by human error, we will provide free repair or replacement services.
