Description

The Allen-Bradley 150-C85NBR is part of the Bulletin 150 of Smart Motor Controllers. This motor controller is specifically an SMC-3 motor controller that provides a variety of control mode for efficient control of motor during start-up, shutdown and idle operation.

The compact design of the SMC-3 controller provides three-phase control, increased intelligence, and unmatched performance in a costeffective package with overload protection, integrated bypass, and motor system diagnostics. DIP switches and a rotary dial make secure setup easy. This controller features an electronic overload with adjustable trip class.

Here are some technical data for the Allen Bradley SMC-3 Controller 150-C85NBR:

• Control Voltage: 24V AC/DC
• Line Voltage：200-480 VAC, 50/60 Hz, 3-Phase
• Output Current: 85 A RMS
• Enclosure Type: Open Type
• Starting Duty: 350%
• Fault Contact: Normally Opened (NO)

The 150-C85NBR has a line operating voltage of 200-460VAC, 3-Phase, along a frequency of 50 / 60 Hz while the motor’s control Voltage is 24VDC / 24VAC. It may be used with line-connected and Delta-connected motors. It delivers a maximum output current of 85 Amperes and comes with Open type enclosure. It has a pair of Normally Open (N.O.) auxiliary contacts that are assignable for OVLD / FLT feedback indication and Normal/Up-to-Speed feedback indication.

The 150-C85NBR has a line input voltage range of 200 to 480 Volts AC at 50 to 60 Hertz and an input current of 85 A.

The controller’s power circuit offers a 2200 Volt AC dielectric withstand, a 600 Volt AC insulation voltage, a 1,400 Volt reverse voltage, and a DV/DT protection of 1000 Volts/µs with 6KV impulse voltage.

The 150-C85NBR offers circuit protection using a 300A non-time delay K5 fuse with 10KA (standard fault limit), a 300A thermal magnetic circuit breaker, with a 10KA standard fault limit, and a 175A high capacity time delay class J/CC fuse.

The 150-C85NBR controller uses a 24 Volt AC/DC voltage for control, and its control circuit offers a 250 Volt AC insulation voltage, a 2.5KV rated impulse, and a dielectric withstand of 1500 Volts AC at 50 or 60 Hertz. It also has a 250 Volt AC or 30 Volt DC auxiliary contact with a 250 Volt insulation voltage, 2.5KV impulse voltage, and 1500 dielectric withstand at 50 to 60 Hertz.

The auxiliary contact has an electromagnetic (E.M.) control circuit, with a normally open relay contact.

The 150-C85NBR has an open-style enclosure and an IP2X rating for use in a Degree 2 Pollution Environment.
