ABB 1SDA053999R1 – Original SACE Emax/Emax 2 Accessory for Low-Voltage Circuit Breakers

The code 1SDA053999R1 is an original ABB SACE spare/accessory, typically used on Emax or Emax 2 low-voltage air circuit breakers. From my experience, 1SDA-series codes are ABB’s SAP-identifiers for precise modules (trip units, signalling modules, releases, or similar accessories). If you’re maintaining an ACB lineup or planning a like-for-like replacement during a shutdown, this kind of genuine part keeps compatibility straightforward and avoids firmware or fitment surprises.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL
• Pre-shipment check: We verify the 1SDA code against your breaker’s nameplate and frame to prevent mismatches.

Key Features

• Genuine ABB SACE part: The 1SDA code ensures traceability and correct pairing with specific Emax/Emax 2 configurations.
• Drop-in compatibility: Designed to fit the intended breaker frame without improvised brackets or wiring changes in most cases.
• Predictable performance: Matches ABB’s platform ratings and environmental specs, which simplifies FAT/SAT documentation.
• Service-friendly: Speeds up maintenance turnarounds by avoiding parameter recalibration beyond the standard ABB procedure.
• Risk reduction: Using platform-matched parts typically prevents nuisance trips or signalling faults that can follow from non-OEM substitutes.
• Stocking strategy: Often stocked for common Emax/Emax 2 maintenance kits; you might notice shorter stop-times versus special-order items.

Technical Specifications

Note: Some 1SDA-coded parts are passive (no supply), while electronic modules may require a control supply (often 24 V DC). We’ll verify the exact requirement for 1SDA053999R1 against your breaker’s nameplate and ABB part matrix before shipping.

• Shunt Opening Release (YO) / Undervoltage Release (YU) – remote trip and safety interlock functions for Emax/Emax 2.
• Motor Operator (MCH) – for electrically charging/tripping the breaker mechanism, useful in ATS or remote operation panels.
• Ekip Signalling / Communication modules – for status relays or fieldbus integration (Modbus/Profibus/Ethernet in many cases).
• Terminal kits and wiring harnesses – tidy retrofit wiring inside the ACB compartment and maintain ABB clearances.

If you’re replacing an existing module, send a photo of the breaker label and the current accessory. We’ll cross-map 1SDA053999R1 to confirm fit on your exact frame size and series.

Installation & Maintenance

• Cabinet requirements: Install within a clean, ventilated switchboard that follows IEC LV panel standards; keep ambient within the breaker’s rating.
• Safety first: Isolate the breaker and verify absence of voltage. Lockout/tagout before removing covers or inserting any accessory.
• Mounting: Follow the ABB Emax/Emax 2 manual for the specific module; torque screws to ABB values; avoid cable stress on small connectors.
• Wiring: Use ferrules and the specified cross-section conductors. Separate control wiring from power paths to reduce interference.
• Commissioning: If it’s an electronic or trip module, perform a function test and, where applicable, update parameters or firmware via the ABB toolset.
• Routine maintenance: Visual checks each shutdown, clean with dry air (no solvents), verify tightness, and re-run trip/signalling tests per site procedures.

Field note: A utilities client swapped an aging signalling module with a 1SDA-coded replacement and immediately cleared intermittent alarm chatter. It seems small, but it removed a recurring nuisance trip risk in their feeder ACB.
