Is ACSELERATOR Quickset free?

Yes. acSELerator QuickSet (SEL-5030) is available as a free download from selinc.com for configuring supported SEL devices. Optional Device Manager / workgroup features may be licensed separately—check the current SEL product page.

What cable connects to an SEL relay?

EIA-232 (RS-232) serial cable, typically DB-9 to the front or rear port. USB-to-serial adapters are common on laptops without a native COM port. Ethernet connections use the relay’s network settings inside QuickSet.

What are the default SEL relay passwords?

On many SEL relays the factory defaults are Access Level 1 = OTTER, Access Level 2 = TAIL, and Access Level B = EDITH. ACC and 2AC are commands that request those levels—not the passwords themselves. Always verify the password table in your relay’s instruction manual; some newer products differ. Change defaults at commissioning.

ACSELERATOR Quickset Getting Started

Quick Answer

acSELerator QuickSet (SEL-5030) is a free download from selinc.com. Install on Windows, create a settings file for your relay model, and connect via EIA-232 serial (often 9600 baud, 8N1 by default) or Ethernet (Telnet, SSH, FTP, or raw TCP depending on the relay and QuickSet communications parameters). Factory-default serial passwords on many SEL relays are OTTER (Access Level 1) and TAIL (Access Level 2)—always confirm against the device instruction manual and change them at commissioning.

Installation

Download SEL-5030 from selinc.com (no paid license key for the base QuickSet package)
Install on a supported Windows version (commonly Windows 10/11)
Launch QuickSet and create a new settings file for your exact relay model and firmware

Connecting

Serial — EIA-232 (DB-9) cable to the front or rear port; default baud is often 9600
Ethernet — Enter the relay IP in QuickSet Communications parameters; Telnet (TCP 23) is common, and many devices also support SSH or other options—match the relay’s enabled service
USB-to-serial adapter — For PCs without a native serial port (use a known-good industrial adapter)

Access Levels (serial / terminal)

ACC is a command that requests Access Level 1 (not a password and not “accounting”)
Access Level 1 — Read metering, events, status, and settings (factory default password often OTTER)
2AC requests Access Level 2; Level 2 allows settings changes (factory default often TAIL)
Access Level B (on many relays) — Breaker/control functions via BAC; factory default password often EDITH

If the password jumper is installed, some relays skip password prompts—still set private passwords before leaving site. Change all defaults for NERC CIP or owner cybersecurity policy.

Interface

QuickSet organizes device settings into folders/tabs for protection elements, communications (DNP3, Modbus, SEL protocol, and others), SELOGIC / logic, and monitoring (metering, Relay Word bits, events). Exact layout depends on the relay model database loaded in QuickSet.
