ABB PS3-4-0 3-Phase Busbar for MS325/MO325 Manual Motor Starters

The ABB PS3-4-0 is a 3-phase busbar accessory engineered to connect up to 4 mountable devices across 12 poles in manual motor starter installations such as the MS325 and MO325 series. Rated for a maximum operating voltage of 600 V AC (UL/CSA) and a rated operational voltage of 690 V, this Pin-connection busbar delivers a rated operational current (Ie) of 63 A with an IP20 degree of protection for safe, efficient phase distribution in low-voltage control panels.

Key Features

  • Connection Type: Pin connection design allows quick, secure linking between adjacent manual motor starter devices.
  • Rated Operational Current (Ie): 63 A supports dependable power transfer across connected phase circuits.
  • Voltage Rating: Maximum operating voltage of 600 V AC (UL/CSA) and rated operational voltage of 690 V for demanding control panel applications.
  • Multi-Device Capacity: Connects up to 4 mountable devices with 12 poles across 3 phases for streamlined panel wiring.
  • Degree of Protection: IP20 rating provides touch-safe operation within enclosed control panel environments.
  • Rated Impulse Withstand Voltage (Uimp): 6 kV for added dielectric strength under transient conditions.
  • Rated Short-Time Withstand Current (Icw): 100 kA short-time withstand rating supports fault-tolerant circuit protection.
  • Compact Footprint: Product net width of 206.5 mm, depth of 13 mm, and height of 31.5 mm at a net weight of 0.087 kg for space-efficient panel layouts.

ABB ABBPS-340 – Frequently Asked Questions

1) Will the ABB PS3-4-0 busbar work with MS325 and MO325 manual motor starters?
That is exactly what the PS3-4-0 is built for. It is a 3-phase pin-connection busbar for MS325 and MO325 series manual motor starters, linking adjacent devices in the panel rather than running individual phase wires to each starter.
2) How many motor starters can one PS3-4-0 busbar feed?
Up to four mountable devices, across 12 poles in 3 phases. If your panel run has more than four starters side by side, you will need an additional busbar for the next group.
3) What current and voltage is the PS3-4-0 busbar rated for?
63 A rated operational current (Ie), with a rated operational voltage of 690 V and a maximum operating voltage of 600 V AC under UL/CSA. The 600 V figure is the one that governs a North American panel build; the sum of the connected starters' load has to stay within the 63 A busbar rating.
4) Which standards does the ABB PS3-4-0 busbar meet for a UL-listed industrial control panel?
The PS3-4-0 is built to IEC/EN 60947-1 and 60947-4-1 and UL 60947-1 and UL 60947-4-1, and it is RoHS compliant per EU Directive 2002/95/EC. Pollution degree is 3, which suits industrial panel environments.
5) Is the ABB PS3-4-0 busbar touch safe for an open control panel?
It carries an IP20 degree of protection, which is finger-safe against contact but offers no water protection. It is intended for use inside an enclosed control panel, not for exposed or wet locations.
6) How much panel width does the PS3-4-0 busbar take up?
Net dimensions are 206.5 mm width, 13 mm depth, and 31.5 mm height, at 0.087 kg. Lay out your DIN rail section with that 206.5 mm run in mind when you are grouping four starters.
7) What fault current and surge ratings does the PS3-4-0 busbar carry?
Rated impulse withstand voltage (Uimp) is 6 kV and rated short-time withstand current (Icw) is 100 kA, so the busbar is not the weak point in a high fault current motor control installation.
8) What is the ABB part number to order for this 4-device 3-phase busbar?
Order it as ABB PS340 (catalog designation PS3-4-0). The numbering follows the pattern: 3 phase, 4 devices.
9) What ambient temperature range can the ABB PS3-4-0 busbar operate in?
Operating range is -20 C to +50 C, with storage from -20 C to +70 C. Panels in hot process areas or unconditioned enclosures should be checked against that 50 C ceiling.
10) Does the PS3-4-0 busbar include auxiliary contact connections?
No. It has zero lateral auxiliary contacts, it is purely a 3-phase power distribution bar. Auxiliary or signaling contacts have to be ordered separately as starter-mounted blocks.
