Phoenix Contact 230 V ac 40kA VAL-MS Surge Arrester Protection Module, DIN Rail Mounting
Phoenix Contact
VALVETRAB® Pluggable single-pole modular lightning surge protector VALVETRAB is a mid-capacity lightning and surge protected designed to protect the low voltage single- or three-phase power supply of your installations.With its strong surge protection, it quenches overvoltage resulting from distant impacts or resulting phenomena.Its pluggable design allows for easy maintenance (surge protector plug combined with a base for electrical connection).Disconnection feature provides continuity of electrical power supply.Features a mechanical indicator which provides a status (operational or out of order) at all times and changeover contacts for alarm reports.Connects in parallel on the mains network and snaps onto a symmetric profile.A wiring bridge allows several modules to be quickly mounted and bridged on the ground connection. Protection class: II Rated voltage Un: 230 V / 400 Vac Max. permanent rated voltage Uc: 440 Vac Max. discharge surge current Imax (8/20 μs): 40 kA Rated discharge surge current In (8/20 μs): 20 kA Protection level (Up): 2.2 kV Protection level Up for 5 kA: 1.75 kV Response time: Leakage current: Short-circuit withstand current Icc with 125 A gL fuse: 25 kA eff Number of 17.5 mm pitch 1 Dimensions (L x H x D): 18 x 97 x 66 mm Max. connection (rigid / flexible): 35//25 mm² Operating temperature: -40 °C → 80 °C Protection level: IP 20 Surge Protection Devices, SPDs (DIN-rail) Voltage surges, often referred to as spikes or transients are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning and can reach up to 6000V, with current surges of over 3000A. The maximum size of the voltage and current surges depends on the location within the building's wiring system. BS7671: 2011 Amendment 1 Sections 443 and 534 cover risk assessment and provides guidance on protection of electronic equipment for installation engineers to follow. The fullest information on lightning and surge protection comes from the BSEN 62305 series of standards. ; Suppressor Type Surge Arrester Protection Module; Maximum Voltage Rating 230 V ac; Mounting Type DIN Rail; Maximum Surge Current 40kA; Series VAL-MS; Length 17.7mm; Depth 54.5mm; Height 52.4mm; Dimensions 17.7 x 54.5 x 52.4mm; Minimum Operating Temperature -40°C; Maximum Operating Temperature +80°C;
