Overview
Circuit breakers
Circuit breakers, 3-pole version
The 3-pole version of the circuit breakers consits pf:
• 2 connecting sets for connecting Cu/Al cables
1)
with cross-
sections of 2.5 ... 95 mm
2
(these terminals are fitted to the circuit breaker)
• 3VT9 100-8CE30 phase barriers
• A set of two mounting bolts (M3 x 30)
• A conductor holder
Characteristic M (motor): motor protection
Circuit breakers, 4-pole version
The 4-pole version of the circuit breakers consists of:
• 2 connecting sets for connecting Cu/AI cables
1)
with cross-
sections of 2.5 ... 95 mm
2
(these terminals are fitted to the circuit breaker)
• 3VT9 100-8CE30 and 3VT9 100-8CE00 phase barriers
• 2 sets of two mounting bolts (M3 x 30)
• A conductor holder (installed in the circuit breaker)

Connection
When connecting the main circuit, the dimensions of the deion-
ization space of the circuit breaker must be observed, depend-
ing on the type of connection
(see pages 2/35 and 2/36)
.
1)
For other connection methods, use connecting parts
(see page 2/9).
