# Industrial Specification: Actuator/Solenoid

## 1. Technical Definition
Electromechanical device that converts electrical signals into mechanical motion within a trip unit.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **12-24 VDC, 0.5-2.0 A, 20-100 N force output, -40°C to +85°C ambient temperature**. Failure boundary: **Coil insulation breakdown at 150°C, plunger seizure at 0.01 mm particulate contamination, permanent demagnetization at 120°C Curie point for ferrite magnets**, Mechanism: **Joule heating (I²R) exceeding 2.5 W/cm² thermal dissipation capacity causes insulation degradation; Lorentz force (F = BIL) reduction due to eddy current losses at &gt;100 Hz switching frequencies**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
