Description
“Cam contactors of the series C155, C156 and C157 are 2, 3 and 4 pole switchgears for AC and DC with cam switching elements of the S307 series for 250 or 300 A of continuous current.
The main contacts can be configured as make contacts, break contacts or as combinations of both. For arc quenching at high loads, electric arc chambers can be used; and for DC voltages over 400 volts, arcing chambers with permanent-magnetic blowout should be used.
The switch state of the main contacts can be reported to higher-level control systems and devices with up to 4 auxiliary switches.”
Robust design, simple maintenance
DC versions with blowout magnets and arcing chambers
Unidirectional DC applications of up to 1,000 volts
Economy resistor or optional electronic economy circuit
Up to 4 auxiliary contacts in auxiliary switch blocks”
