Compared to traditional fuse installation, the UL489/CSA C22.2
No.5-02, UL1077/CSA C22.2 No.235 compliant circuit breakers
listed here assist with the complex task of selecting correct types
and characteristics and offer a less bulky installation solution.
Ourrange of miniature, molded-case circuit breakers, in combination
with our accessories for factory or on-site installation, offer enhanced
control and monitoring capabilities. Installation kits include all parts
and instructions to make the on-site job easy.
We supply UL489/CSA C22.2 No.5-02 and UL1077/CSA C22.2
No.235 compliant 1, 2 and 3-pole-type circuit breakers from 0.5 to
60 Ampere and with type C and D characteristics.
Attachments such as neutral switches, auxiliary contacts and shunt
trips are also available for this system. All accessories for modern
busbar installations are available in compliance with the relevant
UL standards.

Mounting Instructions of Accessories
Applies to BNS... and BST:
The accessory devices BNS... and BST can be installed onthe
right or left.
Mounting
1. Bring the blue knobs of all devices into the “OFF” position
2. Remove grey cover from the switching device and
attachment
3. Insert drive plate between the switching device and BNS...
or BST
4. Insert connecting pin into the knob (insertion depth
approx. 7 mm)
5. Combine switching device and BNS... or BST
6. Screw the devices together (observe correct screw length)
Applies to BAU...
The auxiliary contact BAU... can only be installed
on the right.
Installation
1. Flick the blue switches of all devices to the “OFF” position
2. Remove the grey cover from the switching device and
attachment
3. Combine switching device and BAU...
4. Insert connection screws and connect the two devices by
turning the screws 90°
5. After installation, close and open to check correct operation
Applies to all switching devices
BNS..., BST and BAU...
The load and mains can be connected into either the top or
bottom (Line/Load Reversible).
Design of the terminals
• Optical detection of screw position
• Increased breaking resistance if the screwdriver becomes
jammed
• Universal connecting terminals, suitable for connecting all
known cable lugs such as ring or forked cable lugs and pin
terminals
• Ring cable lugs can be connected by opening the flap and
removing the connecting screw
• Can also be used for applications that require ring cable
lugs (e.g. nuclear power stations)
• DIN EN 50274, VDE 0660-514 compliant protection
against contact with live parts is fully guaranteed

Mounting Instructions of Accessories
Applies to SNS63A and SAU...:
The accessory devices SNS63A and SAU... can be
installed on the right or left. The auxiliary contact H...
UM can only be installed on the right.
Mounting:
1. Flick the blue switches of all devices to the “OFF”
position
2. Remove the grey cover from the switching device
and attachment
3. Insert the drive plate between the switching
device and SNS63A and SAU...
4. Insert the connecting pin into the switch (insertion
depth approx. 7 mm)
5. Combine switching device and SNS63A and SAU...
6. Screw devices together(observe correct screw
length)
Applies to SAU...:
The auxiliary contact SAU... can only be installed on
the right.
Installation:
1. Flick the blue switches of all devices to the “OFF”
position
2. Remove the grey cover from the switching device
3. Combine switching device and SAU...
4. Insert connection screws and connect the two
devices by turning the screws by 90°
5. After installation close and open to check
operation
Applies to all switching devices
SAU..., SNS and SST...
Design of the terminals
• Optical detection of screw position
• Increased breaking resistance if the screwdriver
becomes jammed
• Universal connecting terminals, suitable for
connecting all known cable lugs such as ring or
forked cable lugs and pin terminals
• Ring cable lugs can be connected by opening the
flap and removing the connecting screw
• Can also be used for applications that require ring
cable lugs (e.g. nuclear power stations)
• DIN EN 50274, VDE 0660-514 compliant
protection against contact with live parts is fully
guaranteed
