PISA E-fuse
Available from stockArticle no.:A108.273
The PULS PISA-B-812-B1 is an eight-channel electronic protection module for 24 V DC systems with adjustable channel currents: two channels from 1 to 12 A and six channels from 1 to 10 A, with a total current of up to 40 A. It selectively distributes one power source across multiple circuits and prevents unwanted shutdowns caused by loads with high inrush currents. A common signalling relay, LED status bar and remote reset support straightforward diagnostics and remote operation. Push-in terminals enable fast and reliable installation.

Description
The PISA-B devices are DIN rail mountable eight channel protection modules with integrated electronic fuses for 24V systems. They distribute the current of a large power source to eight output channels each of lower current and therefore allowing for smaller wires to be used. The output current of each channel can be set individually. Channel 1 and 2 are optimized for loads with large input capacitances. Connect such loads to these channels to avoid false tripping or unexpected switch-off such loads. The PISA-B-812-B1 is equipped with a common tripping signaling relay contact that reports tripped channels or channels manually turned off. All PISA-B devices are equipped with push-in terminals, which are optimized for automated wiring. The mechanically robust housing is made of a highgrade, reinforced molded material on the front and of an aluminum body, which permits surrounding temperatures up to +70 °C.
