The PISA Series is available in three form factors: PISA-B (8-channel bus-style modules with alarm relay or coded alarm output), PISA-M (4-channel modular units with adjustable or fixed trip currents), and PISA11 (single-channel precision units covering 1A to 10A with adjustable and NEC Class 2 versions). All variants are designed for 24VDC distribution and integrate directly with PULS power supplies for a complete, coordinated power distribution and protection system.

Main Features:

• Electronic circuit breaking — instant, precise trip response vs. thermal fuse delay
• Selective tripping — only the affected channel trips, leaving other loads running
• Remote reset capability — no need to physically access the panel after a fault
• Three form factors: 8-channel (PISA-B), 4-channel modular (PISA-M), single-channel (PISA11)
• Adjustable trip current options for flexible load protection
• NEC Class 2 compliant variants for limited-power circuit protection
• Alarm relay and digitally coded alarm signal outputs for SCADA integration
• DIN rail mounting for standard panel installation
• CE and UL certified
