ABB PP10 Explosion-Proof Pump Control Relay

Overview

The ABB PP10 is a “Pump-Pak” latching relay field controller – an explosion-proof start/stop control module that switches a pump motor, motor starter, solenoid, or alarm directly from the contact closures of an external level switch, without requiring a PLC or control-room relay logic. Together with its simpler sibling the IR10 interposing relay, it forms ABB’s family of field-mounted relay controllers used to translate a level switch’s on/off signal into a reliable pump-control action right at the point of installation.

Seven Star LLC supplies the ABB PP10 to water treatment, wastewater lift-station, and process-tank operators across Oman and the wider GCC as an experienced supply partner for genuine ABB instrumentation.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.

Operating Principle

The PP10 functions as a latching start/stop control circuit: an onboard miniature switch selects high-level or low-level operation, so the same module can be configured either to start a pump when the level rises to a high set point (emptying a tank) or to stop a pump when the level falls to a low set point (protecting against dry-running). Unlike the simpler IR10, which is a straightforward interposing relay that energizes whenever its input contact closes, the PP10’s latching logic holds the pump ON or OFF state between switch actuations, which is the behavior a level-controlled pump-down or pump-up application actually needs rather than a momentary relay pulse.

Input power (120 VAC standard, with 24 VAC, 24 VDC, or 220 VAC available by ordering code) is fully isolated from the output contacts, so a fault on the field wiring side cannot feed back into the motor-control circuit. The dry relay output is a double-pole, double-throw contact with break-before-make action, rated 10 A at 277 VAC, 15 A at 120 VAC, or 15 A at 30 VDC depending on configuration – sufficient to directly drive a small pump contactor coil or alarm circuit without an additional interposing relay.

Engineering Design of the ABB PP10

The PP10 is housed in a copper-free aluminum, explosion-proof enclosure rated Class I Division 1 Groups B, C, D and Class II/III Division 1 Groups E, F, G, with an additional NEMA 4X rating for outdoor and washdown-prone installations – certifications aimed squarely at hazardous-area pump stations and tank farms rather than benign indoor control panels. Three clearly identified terminal blocks give field technicians a fast, unambiguous wiring point for the level-switch input, the power supply, and the motor-control output, and an optional flange mounting kit simplifies installation directly onto a tank wall, pump skid, or junction box.

Operating temperature is rated from −46°C to 71°C (−50°F to 160°F), and the compact, vibration-resistant construction suits mounting close to the pump or motor it controls, where mechanical vibration would be a concern for a less ruggedly built relay enclosure.

Key Features

• Explosion-proof latching relay controller for direct pump start/stop control from a level switch
• Field-selectable high-level or low-level operating mode via onboard miniature switch
• Isolated power input (120 VAC standard; 24 VAC, 24 VDC, or 220 VAC by ordering code)
• DPDT dry relay output rated up to 15 A at 120 VAC or 30 VDC
• Class I Division 1 Groups B, C, D and Class II/III Division 1 Groups E, F, G hazardous-area certified
• NEMA 4X copper-free aluminum enclosure for outdoor and washdown environments
• Three dedicated terminal blocks for fast, unambiguous field wiring
• Optional flange mounting kit for direct tank, skid, or panel installation
• Vibration-resistant, compact footprint suited to mounting near the controlled pump or motor

Industrial Applications

The PP10 is used wherever a level switch needs to directly start or stop a pump without routing the signal through a PLC or control room – lift stations, sump pumps, wet wells, and process tanks in water and wastewater treatment plants, as well as chemical dosing and storage tank applications across Muscat, Sohar, Salalah, and the wider GCC. It is commonly paired with ABB buoyancy or vibrating-fork level switches, where the switch provides the level signal and the PP10 provides the certified, hazardous-area-rated power-switching action.

As a trusted ABB supplier, Seven Star LLC supplies the PP10 correctly matched to the customer’s level switch, motor starter rating, and area classification, rather than a generic relay module that may not carry the certifications the installation actually requires.
