PULS PISA – electronic fuses
The PISA family from PULS offers a range of adjustable electronic protection modules for safe, reliable and well-structured power distribution in 12 V and 24 V DC installations.
These compact DIN-rail solutions combine selective channel protection, fast shutdown and high compatibility with capacitive loads, significantly increasing the availability of machines and systems.
Within the PISA family, PISA-M supports four independent channels with fixed or adjustable current limits (1–8 A), slow/fast tripping and integrated Power Supply Overload Protection.
PISA-B extends this concept to eight channels (1–10 A / 12 A), featuring channel current indication via LED matrix, integrated positive and negative terminals, and options for either an alarm relay (B1) or digital coded signal output (B4).
All modules offer local operation and status LEDs, are designed for high operational reliability up to +70 °C, and are UL-certified, including NEC Class 2 variants within the range.
