Product Overview
Three variants from 630A to 800A for large-scale PV plant main incomers, transformer secondary protection, and high-capacity AC distribution. At 690V AC, 800A handles approximately 960kW — suitable for multi-inverter PV plant AC collection nodes or large battery plant AC main switches.
800V and 1000V AC ratings extend the application beyond standard 690V distribution into high-voltage industrial AC systems connected to utility-scale PV or storage facilities.
800A switches cover large centralised inverters or parallel inverter groups. At this current level, confirm bus bar cross-section and terminal torque specification — inadequate contact surface area is a common source of overheating in high-current switchgear during sustained inverter output at rated power.
Applications
Inverter output protection
AC distribution boards
EV and PV support circuits
Residential and commercial electrical BOS
Frequently Asked Questions
What is a typical application for 800A AC MCCB in a PV plant?
At 690V AC, 800A is the main incomer rating for a PV collection panel aggregating around 900-960kW of inverter output. It also appears as a bus section breaker, transformer secondary protection, or main switch in large BESS AC distribution.
Does OmniSol supply motor-operated MCCB accessories?
Motor-operated and shunt-trip accessories are available for some MCCB frames. Confirm the required accessory type, control voltage, and communication protocol at RFQ and we check availability for EKM6-800H.
