Formula Sound 071 32A Contactor with Interface for Sentry Sound Limiters

Name: Formula Sound 071 32A Contactor with Interface for Sentry Sound Limiters
Brand: Formula Sound

The 071 is the matching contactor for the Formula Sound Sentry limiters: it is the part that actually disconnects the mains when the Sentry trips. The Sentry holds the contactor closed with a low-voltage signal over a simple 2-core link; when the room goes over the limit for too long, the signal drops, the contactor opens and the ring feeding the amplifiers and music equipment goes dead until the Sentry is reset. It is a single-pole, normally-open, fully fused unit in its own enclosure, ready for an electrician to wire into the sound system's supply.32ARating · Fused1 phaseSupply · 220-240 VNOContact · Single pole2-coreControl · Low voltageElectrician installationThe 071 switches mains and must be installed by a qualified electrician to BS 7671, indoors, fixed to a wall or board (not free-standing). No mains is connected to the low-voltage interface board. It is for single-phase supplies; for two separate rings use the 071D dual contactor, and for larger loads the 071 can switch a further contactor.FeaturesMatching contactor for the Sentry MK2 (073) and Sentry Lite (152)32A rating, fully fused with a 10 x 38 mm HRC gG fuseSingle-pole normally-open: fails safe, power off when the Sentry tripsLow-voltage interface board, polarity not critical, bell wire is fine20 mm conduit knockouts plus grommeted holes for the control cableFour base fixing holes with fixing template suppliedLower fuse ratings can be fitted to suit the circuitSpecificationsTypeSingle-pole normally-open contactor with low-voltage interfaceRating32ASupplySingle phase, 220-240 V ACFuse10 x 38 mm HRC gG, 32A (lower rating can be fitted)Control signalLow-voltage DC from the Sentry (under 18 V, under 100 mA)Compatible withFormula Sound Sentry MK2 (073) and Sentry Lite (152)Entries20 mm conduit knockouts; grommeted low-voltage cable holesDimensions260 x 155 x 85 mmUseIndoor, fixed installation, not for domestic usePart number071Show more
