The SP-JBL is a professional quality junction box designed to easily accommodate power and/or heating cable entry and connection. It is supplied complete with an internal assembly of DIN rail-mounted terminals with easy identification of correct wiring orientation. There are enough terminals for 1 x power and 3 x heater circuits. The enclosure is made from tough weatherproof polycarbonate which generally has better environmental (UV) resistance than ABS and uses 4mm² terminals for easy insertion of wiring. There are enough terminals to easily accommodate 3 heater circuits without the need to ‘gang-up’ more than one circuit per terminal. Typical application/use is to connect POWER to or TEE/SPLICE up to 3 heater circuits.
