All-New PISA-B Multi-Channel Electronic Circuit Breakers from PULS
The all-new PISA-B multi-channel electronic circuit breakers help you to optimize the availability of your DC 24 V systems right away and grow with your application.

PISA-B. The next generation of electronic circuit breakers. Protect (P), Inform (I), Secure (S), Assist (A).

Protect (P)

Selective tripping of overloaded channels

In the event of a fault, PISA-B disconnects the affected channels only and ensures constant power supply to the remaining loads. This means individual faulty connections can be rapidly identified, isolated and rectified.

Two different output types

PISA-B features two types of output channels. Channel 1 and 2 are ideal for high capacitive loads up to 100 mF and allow peak currents up to 12 A. Standard loads with up to 20 mF can be connected to channels 3 to 8 and are supplied with up to 10 A. You can choose between slow or fast tripping characteristics for all channels.

Inform (I)

Instant current monitor

You can use the instant current monitor with LED technology at the front of the device to analyse and reset individual channels. The LED matrix helps to understand and evaluate your loads, detect peak currents and change your settings. 

Alarm signal

The electronic circuit breaker informs you about tripped channels via an alarm relay contact (PISA-B-812-B1, PISA-B-8CL2-B1).  An optional “digital coded alarm signal” provides information about the tripping status of individual channels (PISA-B-812-B4, PISA-B-8CL2-B4)

Reset feature

The additional reset relay contact allows switching the device ON and OFF or resetting all tripped channels remotely.

Secure (S)

PIN protection

The new design of the PISA-B helps to avoid accidential operating errors or manipulation via a PIN protection feature. The settings can be locked with a 4-digit PIN code via the user interface on the front of the device.

Fail-safe switch

The fail-safe function is a back-up protection feature of the PISA-B. If one of the channel switches fails to open, the fail-safe function kicks in. Therefore an electronical switch is used instead of a traditional melting fuse. The electronic circuit breaker monitors the total current and can react much earlier, if the current becomes too high. This feature can save your lines from overheating.

Assist (A)

Compact design

The compact product design helps you to save space. The electronic circuit breaker includes plus and minus distribution terminals, with a total width of only 52mm – that means 6.5mm per channel.

Modular design

PISA-B allows an easy and fast expansion of your system. Up to 8 devices can be connected in parallel via bus bars. This sums up to 64 channels in total.

Push-in terminals

PISA-B also assists you with a tool-less push-in technology. The terminals are optimized for automated wiring processes.

All-New PISA-B Multi-Channel Electronic Circuit Breakers from PULS

PISA-B gives you more of everything. Except effort.

PISA-B is the most efficient electronic circuit breaker (ECB). It distributes the current, protects your loads from over-current or short-circuits and monitors the operating status in DC 24 V systems.

The 8-channel programmable capability can identify and isolate individual faulty branches. It shuts down the affected channels only and secures the constant power supply of the remaining loads.

An integrated data monitoring reports the operating status to a PLC or control center. The electronic circuit breaker also alarms in case of an error and allows a remote reset of the channels.

The new PISA-B is based on a modular product design. Up to 8 PISA-B electronic circuit breakers can be connected in parallel by using bus bars. This results in up to 64 channels.
