GEYA GYHO8 4P 63A circuit breaker

The GEYA 4P (4-pole) modular network switch is a reliable and compact solution for manually switching the power supply between two independent power sources. It is typically used to manually switch a building from the main supply (distribution network) to a backup source (backup generator, photovoltaic system or backup battery system) and back again.. Thanks to its 4-pole design, the switch connects and disconnects all three phase conductors (L1, L2, L3) simultaneously with the neutral conductor (N), ensuring complete galvanic isolation of both networks without the risk of voltage leakage into the backup source. The package also includes removable protective terminal covers to prevent accidental contact with live parts.. The switch features a clear, modular design for a DIN rail with a control lever and has three stable positions (I – 0 – II). The central ‘0’ position ensures complete disconnection of the load from both sources (known as ‘forced break’ switching), which protects both the appliances and the backup generator during on-load switching.. MAIN ADVANTAGES AND APPLICATIONS:. Complete 4P isolation: Switches all 3 phases + neutral conductor (N) for maximum safety when operating on generator power.. Position 0 (safe disconnection): The central off position prevents the simultaneous connection of two unauthorised sources and protects the generator from reverse current from the mains.. Compact modular design: Designed to the dimensions of standard circuit breakers for easy installation in any switchboard.. Intuitive lever operation: Smooth and reliable switching via a lever with clearly defined positions I – 0 – II.. Easy installation: Designed for mounting on a standard DIN rail (TH35) in standard surface-mounted or flush-mounted distribution boards.. Wide range of applications: Ideal for detached houses, workshops, agricultural buildings, commercial premises and photovoltaic installations (PV) with a backup generator..
